The main objective of the LECLERC square is to revitalise the city centre and, more precisely, the lower city with a qualitative layout of the living environment, a reasoned management of spaces with identification and dedicated use to strengthen the social link as well as a noticeable incentive on the uses tending to the energy transition. Also, the establishment of plantations with low water consumption but also a reasoned and integrated management of stormwater and runoff to green spaces and large joints absorbing on parking spaces bring added environmental value.
